ENGINE COOLANT TEMPERATURE SENSOR INSPECTION

PROCEDURE

  1. INSPECT ENGINE COOLANT TEMPERATURE SENSOR

    1. A287154C07

      *a

      Component without harness connected

      (Engine Coolant Temperature Sensor)

      *b

      Resistance (kΩ)

      *c

      Temperature (°C)

      *d

      Acceptable

      Measure the resistance according to the value(s) in the table below.

      Standard Resistance

      Tester Connection

      Condition

      Specified Condition

      1 - 2

      Approximately 20°C (68°F)

      2.32 to 2.59 kΩ

      Approximately 80°C (176°F)

      0.310 to 0.326 kΩ
      Note:

      When checking the sensor in water, keep the terminals dry. After the check, wipe the sensor dry.

      If the result is not as specified, replace the engine coolant temperature sensor.
